Abstract (en)
[origin: EP3733611A1] An apparatus and method for wastewater or sludge treatment including a reactor tank (5), a dosing unit (3) for introducing a magnesium chloride precipitant into the reactor tank and a degassing unit (7) for degassing the wastewater or sludge within the reactor tank (5) at reduced pressure. The inventive method mixes the magnesium chloride, so as to precipitate struvite, prior to degassing the wastewater or sludge, so as to extract carbon dioxide or methane from the wastewater or sludge.
